Ron could also be a key character. He might be initially jealous of Harry's OP pet but then grows to accept it and even helps Harry in taking care of it. For instance, if the pet is a large and difficult - to - manage magical beast, Ron's strength and loyalty would come in handy when it comes to tasks like building a proper shelter for the pet or finding the right kind of food for it.
One popular character could be Hermione. In these fanfictions, she might be the one who helps Harry understand and train his OP pet. For example, if Harry has a magical creature that can manipulate time, Hermione would use her vast knowledge of magic to figure out how to control this power and not let it disrupt the fabric of the wizarding world.
Hermione could be a popular character. In some fanfictions, she might accompany Harry to the Underworld and use her vast knowledge to help them solve problems. For example, she could be the one to decipher ancient Underworld texts that hold the key to their mission.

Definitely Ginny. Since she's Harry's love interest in the original series, in the fanfiction about them growing up, she has a big role. She could be shown as a strong, independent witch who is equal to Harry in many ways. Draco Malfoy is also a character that features a lot. Sometimes, fanfiction explores his redemption arc further as he and Harry have to interact in the post - war wizarding world.
Snape can be a prominent character. Given his complex relationship with Dumbledore and Harry, his perspective could add a lot to the story. He might have some insights into Dumbledore's actions that Harry doesn't know about, and his reactions to Harry's blaming could vary from being scornful to having a moment of understanding. Luna Lovegood could also be a part of it. Her unique view of the world might make her offer some different viewpoints on the situation between Harry and Dumbledore.

They could create new and even more spectacular magical pranks specifically aimed at Umbridge, like turning her office into a never - ending maze of trick stairs and hidden rooms filled with various magical creatures that drive her crazy.

Ron could also be a significant character as his reactions to Harry's transformation can add humor and depth to the story. Also, Luna Lovegood might be interesting as she could have some unique insights or interactions with Harry in her new form.
There could be the mafia boss. He might be a tough and shrewd character who takes Harry under his wing at first but later becomes suspicious of Harry's actions.
